DK 157057 B

BACKGROUND OF THE INVENTION The invention relates to a method for portion brewing of beverages, such as freshly brewed coffee, in which an external beaker is charged with a quantity of flavoring, such as ground coffee, and water, as well as other ingredients, such as sugar and surface, . The invention further relates to an apparatus for carrying out the method.

When brewing coffee in the presence of flavors, such as freshly ground coffee and tea leaves which cause grumble after brewing, it is known that the grumble gives rise to problems of disposal and cleaning. This is especially the case in vending machines in which a large number of batches of ready-to-drink beverages can be produced. If these sales-15 vending machines incorporate the possibility of producing ready-to-drink flavors that give rise to grumble, 'these vending machines require far more frequent servicing than vending machines which do not occur.

The object of the invention is to provide a method and apparatus which opens the possibility of making beverages, such as freshly brewed coffee, without the necessity of removing grumble and cleaning as a consequence of the occurrence of the grumble.

This is achieved by the method according to the invention being characterized in that, after filling the outer cup, a second inner cup having a filter-acting bottom is placed on top of the farthest outer cup with the bottom resting. directly on the surface of the liquid contents, and that the two jugs are then compressed simultaneously with the liquid being driven during filtration through the bottom of the inner beaker.

Hereby it is obtained that a package consisting of two interconnected cups is provided which both contains the finished brewed beverage and the associated grumble which is locked in between the two cups and is thereby removed from e.g. a vending machine along with the gasket. The two jugs may be appropriate

2 is arranged so that, under snap action, the inner cup locks into the outer cup in the same manner as known beverage cup lids in commonly used beverage vending machines, e.g. the type described in Danish Patent Application No. 3778/84.

During brewing, only the cups come into contact with the mixture of flavoring and water, and as a result of this, no special requirements for cleaning are made due to the presence of unresolved 10 grams.

An apparatus for dispensing the method wherein the apparatus has means for dispensing cups and portion-matched quantities of ingredients, and wherein the apparatus has means for receiving a colored outer cup while being refilled with a liquid consisting of the desired ingredients, according to the invention, are an essential ingredient in the fact that it has means for taking up and disposing of another inner beaker having the liquid outer cup in question. a bottom 20 acting on top of the outer cup with the bottom facing on the liquid surface of this cup, said means for receiving said outer cup and said means for receiving said internal cup to provide a pressure difference between said interior of the inner cup and between the cups they lie freely! of the liquid surface, and that the apparatus has means for compressing the two cups while maintaining said pressure difference in such a way that the liquid in the outer cup is filtered into the inner cup.

30 Hereby it is obtained that an appropriate apparatus for carrying out the process is provided.

In particular, according to the invention, the apparatus may be characterized in that the apparatus has means for receiving and placing, after the first outer cup has been filled with the liquid in question, another inner cup having a filter-acting bottom on top of it. outer cup with bottom resting on top 3

DK 157057 B

on the liquid surface of this beaker, the means for receiving the outer beaker and the means for receiving the inner beaker are arranged to be able to cause a pressure difference between the interior of the inner beaker and the portion of the liquid surface lying between the beaters and the apparatus has means for compressing the two jugs while maintaining said pressure difference in such a way that the liquid in the outer jug is filtered into the inner jug.

According to the invention, the means for receiving the second inner cup can comprise a sleeve-shaped part which is arranged at one end, at least during brewing, to be lined in airtight engagement with an adjacent end of the means for receiving the outer cup. while at the other end 15 it is adapted to be airtight to cooperate with an end wall which, at the same time, compresses the cups close to the upper periphery of the inner cup, and which in the area, radially within this periphery, has an air outlet passage, and wherein the means for receiving the first outer cup simultaneously are arranged to form an airtight, circumferential wall between the outer side of the outer cup and the sleeve-shaped portion and connect substantially airtight to the outside of the outer cup. Hereby a particularly simple embodiment of the apparatus according to the invention is obtained.

25

The means for receiving the outer cup may in particular simply be a ring which encloses the first cup during the compression, while the end wall opposite to the sleeve-shaped part is a coaxially displaceable piston which is adapted to press the inner cup coaxially into the outer cup.

According to the invention, the means for receiving the first outer cup may comprise a coaxial with the cup displaceable piston supporting the cup, as well as a circular roller membrane which forms the airtight connection between one end of the sleeve and the peripheral piston, 4

DK 157057 B

while the end wall at the other end of the sleeve-shaped portion is held stationary in engagement therewith and supersedes the second cup, while the piston displaces the first cup around the second cup. Hereby, another suitable embodiment of the apparatus according to the invention is obtained.

Finally, the invention relates to a beaker for use in the manufacture of a drink, such as freshly brewed coffee, which is distinctive in that it has a base formed with such perforations as to permit passage of the potable ones! of the liquid prepared during brewing. Such a beaker is suitable for use as the internal beaker of the above apparatus according to the invention.

The invention is explained in more detail below with reference to the drawing, in which fig. 1 is a schematic view of a vending machine with a first embodiment of an apparatus according to the invention, seen in perspective, 20 with parts removed for clarity; FIG. 2 is a vertical section through a package for receiving a freshly brewed beverage, seen at various stages during the brewing process, together with its parts, FIG. 3 is a schematic perspective view of a vending machine with another embodiment of an apparatus according to the invention, with parts removed for clarity, and FIG. 4, like FIG. 2 in succession during the brewing process of the FIG. 3.

The FIG. 1, which is indicated by the general reference numeral 1, has, as indicated, a cabinet-shaped cabinet 2, 35 in which is arranged an apparatus which is provided with the general reference numeral 3, which is adapted to produce ready-to-use portions of beverages. The car in question 5

DK 157057 B

mat 1 is of the same type as that described in Danish Patent Application No. 3778/84, and comprises a beaker dispenser which is provided with the general reference numeral 4 and from which, upon activation of the dispenser, the beaker is delivered individually to a beaker 5. filling device provided with the general reference numeral 5. During rotation of this filling device, filling of a cup 6 with a desired beverage is ensured. After filling, the beaker is dispensed via an opening 7, which is only indicated in figure 1.

10

During the rotation of the filling device from the dispensing of the cup 6 at the cup dispenser 4 to the opening 7 on the front of the dispenser, the cup passes under a number of ingredient delivery devices 8, 9, 10 and 11. These ingredient dispensing devices contain in a generally known way a container of flavors. , such as coffee, sugar and powder for the manufacture of soda, and each has its own delivery mechanism. These ingredient dispensing devices are of generally known type. After the passage of the ingredient dispensers 8-11, the beaker 5 is weighed under a water dispensing device 12 which is also of the conventional type. After the water delivery device, the beaker 6 passes a filtration device which is provided with the general reference numeral 13 and which is arranged to be activated when it is a beverage to be filtered and implies that a residue of grumble or filter cake occurs.

The filtration device 13 comprises, as shown schematically in FIG.

1, a further beaker dispenser 14 adapted for activating dispensers another beaker 15 into a sleeve-shaped brew cylinder 16. This brew cylinder 16 is pivotally mounted via a radially projecting arm 17. a vertical axis 18. Upon actuation of the filtration device 13, the brewing cylinder 16 with the beaker 15 is rotated over the pre-filled beaker 6 in such a position that the brewing cylinder 16 extends coaxially with the beaker 6. In FIG. 1, the brewing cylinder is shown in two positions, namely 6

DK 157057 B

partly under the beaker dispenser 14 and partly in the coaxial position relative to the beaker 6, it is noted that in the preferred embodiment only a single brewing cylinder 16 is used, so that reciprocation is moved between the two aforementioned positions. . At the position of the loading device 5, in which the cup 6 is coaxial with the brewing cylinder 16, a piston device 19 is provided with an associated motor 20. The piston rod 21 of the piston device 19 extends coaxially with the cup 6 in the current position and is arranged 10. to be able to shift back and forth in this direction.

In FIG. 2, portions of f of the iteration device 13 are shown more detailed at different successive stages during its operation. Various stages are shown in Figures A, 15 B, C, D, E and F. As shown in Figure A, which shows the cup 6 filled with the desired liquid, consisting of a mixture of flavors and hot water, etc., the cup is 6 hung in a cup holder ring 22 of the same type as that used in the vending machine disclosed in the above-mentioned Danish patent application 20 No. 3778/84. The cup 6 is referred to hereinafter as the outer cup.

In Figure B, the outer cup 6 is seen suspended in the cup holder ring 22 in a position immediately adjacent to that in which the brewing cylinder 16 is coaxial with the outer cup 6. As can be seen from Figure B, the brewing cylinder 16 contains a the second beaker dispenser 14 hydrating beaker 15 which, during the movement of the brewing cylinder 16, is supported by a suitable support plate 23 which, for clarity, is not shown in FIG. 1. This support plate 23 is formed so that when the brewing cylinder 16 is coaxial over the outer cup 6, the supported cup 15 can freely fall down on the liquid surface 24 on the liquid in the outer cup 6.

For convenience, the second beaker 15 is then referred to as the 35 inner beaker. In Figure C, the inner beaker 15 is seen with the bottom resting directly on top of the liquid surface 24. As mentioned, the brewing cylinder 16 is coaxially with the outer beaker 6 and directly below the piston device 19.

DK 157057 B

The inner cup 15 is not formed in a specific manner with a bottom which is so perforated as to allow filtering of the beverage from the outside to the inside, as described in more detail below with reference to Figure 5 (fig. 2).

The piston rod 21 of the piston device 19 carries at its lower end a piston 25 which externally carries a circumferential sealing ring 26, and on the downward side along a circumferential zone is arranged to engage sealingly with the upper edge of the inner beaker 15. As shown in the drawing, the plunger 22 has a cone-shaped projection which is dimensioned to fit into the mouth of the inner beaker 15.

15 shows the piston device 19 in the activated state. As can be seen, in this state, the outer cup 6 via the cup holder ring 23, as indicated by a pie 28, has been displaced upwards until the cup holder ring 22 has engaged tightly with the adjacent end of the brewing cylinder 16. For this For purpose, the cup holder ring 22 suitably has a circumferential cut 29 with a suitable seal ring 30.

Similarly, to ensure tight-fitting engagement between the cup holder ring 22 and the cup 6, a circumferential 25 sealing ring 31 is provided on the inside of the cup holder ring 22. The displacement of the beaker ring 22 is not achieved in any way with the drive mechanism which already drives the beaker ring back and forth in a vertical direction during the rotation of the filling device 5.

30

From above, the plunger 25 is simultaneously moved vertically downwards in the direction shown by a p. 32. Including the plunger 25, partly in tightly engaging engagement with the inner side of the brewing cylinder 16 and partly in tightly engaging engagement with the upper edge of the inner cup 15. . The cone-shaped projection 27 serves to guide the inner cup 15 into a correct position, partly in relation to the outer cup 6, and partly in relation to the outer cup 6.

DK 157057 B

a stamped 25. As can be seen, between the two jaws 15 and 6 there is provided an airtight space 33, whose internal pressure affects them! of the liquid surface 24 located around the inner cup 15.

. 5

As continued movement of the plunger 25 downwardly, as shown in Figure E, the airtight space 33 will be reduced at the same time as the inner cup 15 is pressed down into the outer cup 6. The resulting overpressure in the airtight space 33 10 will affect the liquid surface 24 in such a way that the liquid is filtered into the interior of the inner cup 15 while passing through the bottom acting as a filter. This filtration is indicated by arrows 34 and 35 and arrows 36 and 37 in the enlarged section of the inner cup 15 shown in Figure E in the immediate vicinity of its bottom 38. As can be seen from FIG. 2, the plunger 25 is provided with a safety valve 39 which, via a passage 40, communicates with the airtight space 33. This ensures that the pressure in the airtight space is maintained at a predetermined pressure. In order to simultaneously ensure that the air can freely flow out from the interior of the inner beaker 15, a through opening 41 is provided in the plunger 25.

When, as shown in Figure F, the plunger 25 has reached its lower 25 position, the inner cup 15 has been pressed so far into the interior of the outer cup 6 that between the two cups there is essentially only one filter cake consisting of e.g. coffee grounds at the same time that the outer rim of the inner beaker 15 is pressed into engagement with the outer rim of the outer beaker 6. The outer rim of the inner cup 15 is suitable for this purpose in such a way that it can snap into the outer edge of the outer cup 6 under snap action.

The beverage in question is now ready to be brewed for consumption, 35 and the resulting pack 42 consisting of the compressed cups 6 and 15 can then be dispensed via the aperture 7 of the machine in a generally known manner after lowering the cup holder.

DK 157057 B

The ring 22. Along with the pack 42, there is also the filter cake 43, which in this way is easily provided by the road without the inconvenience of the person who is to enjoy the drink in question and who is to maintain the vending machine. During the brew, no one comes! of the 5 appliances in connection with the brewed beverage, and as a result, brewing does not impose special requirements for cleaning.

After the brewing is completed, the piston device 19 is moved back to its output position in a level above the brewing cylinder 16, and 10 the brewing cylinder 16 is even moved back to its initial position under the second beaker dispenser 14. The movement of the brewing cylinder 16 can be carried out in any desired manner. Eg. it can be inserted into a correct position with respect to the outer cup 6 by means of a projection 45 cooperating on a brewing cycle 1 on the outer side of the bottom 16 with a carrier 46 on the filling device 5 (see Fig. 1). .

In FIG. 3, another embodiment of a dispenser for dispensing of brewed beverages is schematically shown. This vending machine also has a cabinet-shaped cabinet which is provided with the general reference numeral 50. Also, this vending machine is of the type in which the finished beverage is manufactured in the interior of the cabinet 50 and, after completion, is passed through an opening on the front of the cabinet. . The beverage product in question is manufactured by means of an apparatus comprising a beaker dispenser provided with the general reference numeral 51, which is adapted to dispense with exterior cups 52 of the same type as the outer cup by appropriate activation. cup 6 in the embodiment described above. The outer cups 52 are dispensed 30 to a filling device provided with the general reference numeral 53, and are passed through it after the subsequent ingredient dispensing devices 55, 56, 57 and 58 and a water supplying device 59 in the same manner as described. above. Following the water supply device 59, the outer beaker 52 of the feeding device 53 passes another beaker dispenser, which is provided with the general reference numeral 60, which is adapted to dispense inner beaker 61 of the same type as the internal beaker 15 described above.

DK 157057 B

The filling device 53 is constructed in a slightly different manner from the loading device 5 described above. It consists of a rotor 62, in which there is a beaker chamber 63 for receiving an outer baking 52 during the rotation of the filling device 53 over its vertical center axis 64.

In FIG. 4, the beaker chamber 63 is shown in various situations during the rotation of the filling device 53. The baking chamber 63 is downwardly delimited by a vertically displaceable piston 65, 10 which carries at its upper end a circular support plate, which serves partly to support the outer baking 52 of the baking chamber 63, and partly serves to secure a circular roller membrane 67, the outer circumferential periphery 68 is fixedly closed between two sleeve-shaped or cylindrical, coaxially positioned rudder pieces 69 and 70, which together define the baking chamber 63. In the wall of the upper rudder 69 there is a safety valve in 1, which is provided with the general reference numeral 71, which is associated with the baking chamber.

During the rotation of the filling device 63, the piston 65 ensures that the outer baking 52 has the desired location, seen in the vertical direction. This is effected by vertical displacement of the piston 65 by means of an associated motor 72 (see Fig. 3), which is arranged in no way shown to actuate the piston rod 73 belonging to the piston 65, as in fig. 3 is shown in three different situations with corresponding arrows 74, 75 and 76, which indicate the different shear directions.

The beaker chamber is shown in FIG. 4 shown in four different situations 30 in the form of depictions provided with reference numerals H, I, J and K. In Figure H, the baking chamber 3 with the piston 65 is placed in such a position that the upper edge of the outer baking 52 aligns with the rotor 62 top side, i.e. the upper rim 77 # of the sleeve-shaped rudder piece 69. In this condition, the baking chamber 63 is located during receiving the outer baker 52, and during the passage of this baker 52 the various ingredient dispensing devices 56-58 and the water supplying device 59.

After the passage of the water delivery device 59, soin shown in Figure H, the outer beaker 52 has been filled with a liquid soin containing the desired ingredients. In the case of ingredients whose flavor constitutes grim, the second beaker dispenser 60 is dispensed to dispense an inner beaker 61 when the beaker chamber 63 is coaxially adjacent to this beaker dispenser 60. Next, the plunger 65 is lowered, so that the upper rim of the inner beaker 61 aligns with the upper rim 77 of the beaker chamber after it has moved into place with its bottom 10 78 resting on the liquid surface 1 of the outer beaker 65. The inner beaker 65 61 passage down to the correct position on top of the liquid surface 79 is controlled by the surrounding sleeve-shaped rudder piece 69. With the beaker chamber 63 in the state shown in FIG. 1, the beaters 15 52 and 61 are moved to a location directly below a pressing plate 80 which, as shown in FIG. 3, is secured to a piston cylinder of the end arrangement 81, which allows vertical displacement of the pressing plate 80. This pressure plate 80 has on the underside a cone-shaped projection 81 which fits precisely in the end 20 of the mouth of a inner cup 61. Around this conical stub-shaped projection is found a suitable sealing ring 82 which is adapted to form a sealing connection with the upper rim 77 of the cup chamber and the upper edge of the inner cup 61, when the pressing plate 80 with appropriate activation has been 25 is lowered to abutment thereof, which occurs immediately after the cups 52 and 61 have been fastened under the pressing plate 80.

Centrait in the compression plate 80 is a through hole 83.

When the pressing plate 80 is tightly engaged with the upper edge 77 of the beaker chamber 63 and the upper edge of the inner beaker 61, an airtight space 84 is provided between the two beakers. This space is delimited downwardly by the said roll diaphragm 35 67. Upon subsequent activation of the piston 65, so that it moves vertically upwards, this is done, just as with the one shown in FIG. 1 and 2 compression of the insert 12

DK 157057 B

three cups 61 and the outer cup 52 simultaneously with filtering through the bottom 78 soin blades of the cup 61 by the reduction of the airtight compartment 84. The pressure in the airtight compartment 84 is maintained upright at an appropriately predetermined pressure by the safety valve 71, and the air in the interior of the inner cup 61 can, during filtration, freely flow out through the through housing 83 in the pressing plate 80.

Figure J shows the beaker chamber 63 after filtration is completed. Here, the plunger 65 is seen in its rearmost position and the pressing plate 80 in the pressed position against the outer edge 77 of the beaker chamber 63.

When the filtration is completed, the beverage 15 is ready for delivery. First, the pressing plate 80 is raised, and then the beaker chamber is removed from the pressing plate 80. Next, "the finished gasket 85 consisting of the inner cup 61 and the outer cup 52 is raised in compressed state with the filter cake 86 locked between the two cups and the finished cup. This latter raising of the gasket 85 occurs until the support plate 66 aligns with the outer edge 77 of the goblet chamber 63, as shown by reference numeral 87 in Fig. 3. In this condition, the gasket 85 upon continued rotation of the filling device 53, automatically 25 is driven out through the opening of the cabinet 50 and out to the customer by means not shown.

It is noted that both in FIG. 1 and 3, a number of beaker chambers are shown, but each filling device contains only one beaker chamber, so that only one drink is produced at a time.

The apparatus described and the method of preparation of ready-to-drink beverages, as mentioned, employ 35 cups with a bottom acting as a filter. Such a cup can be produced in many different ways, e.g. by spray casting into one of the same material or by vacuum molding.

Another possibility is that the bottom may consist of nylon fabric or other suitable separate mesh material which is attached to a bottomless container. 5 The other parts of the appliance are made from materials which are generally known in the machines in question. The invention has been described with reference to preferred embodiments. However, many changes can be made. Eg. In FIG. 2 and 4 showed successive states during a brewing process also in one place without the use of any rotary filling device. The most important thing is that after the outer cup has been filled with a liquid, the outer and inner cups are compressed under such pressure conditions that the liquid is filtered up through the bottom of the inner cup. After brewing, the package containing the beverage in question may e.g. manually removed from the compression site. In that case, the 20 brewing apparatus in question will be of a particularly simple construction, which will be suitable for the production of filled packages on a relatively small scale. Said pressure conditions can also be provided, if desired, by means of a vacuum pump (not shown) which sucks the air out of the inner beaker, e.g. 25 via the device shown in FIG. 2 in the piston 25. This allows the provision of the airtight space around the space between the two beakers. of the liquid surface is avoided, which means that only a tightly sealed seal must be used between the piston 25 and the upper edge of the inner cup 15. 30 Patent claims.
